Hi,
how can I write an action
getInt :: IO Int
that works like
getLine :: IO String
but for Int instead of String. I know that I can read the input with getLine and then convert it by using read, but don't know how to write it as an action. I tried
getInt :: IO Int
getInt read <- getLine
but that doesn't work.
